Keysight PXI Digital IO Module Introduction
The Keysight M9187A PXI Digital IO Module provides 32 high output voltage and
current channels along with 32 dual variable threshold input channels.
-
Each of the output channels can drive the output either high (sourcing up to
0.4A) or low (sinking up to 0.5A), or three-stated (off). All output channels are
protected against over-voltage, over-current, and thermal overload. An
external power supply is required for high-side driving.
-
The 32 input channels are read by comparing the input DC voltage to two
threshold voltages that can be set between 0.3 and 50Vdc. The thresholds
can programmatically be set with 12.5mVdc resolution, permitting input
testing against the system thresholds that define a logic low or logic high.
Note that the two thresholds are the same for all 32 input channels -- the
thresholds are not independently set for each input channels.
-
The inputs can be connected directly to the outputs without risk of damage,
allowing module configuration for operation as 32 channels of independent
input and output or as 32 channels of configurable I/O.
-
User connection is a 78 pin D-type connector on the module front panel.
Keysight also supplies software drivers allowing you to support the module in all
popular PXI chassis’ and programming environments. Soft Front Panel software
allows you to exercise the channels for test purposes.
